Umbrella-like Device Using Flexible Ribs

ABSTRACT

This disclosure describes an umbrella-like device to protect an object (e.g., person, an area of land) from an article (e.g., precipitation, sun rays, falling debris). In some instances, the device includes flexible ribs attached to short restraining lines stored within a tube. When the ribs are pushed out of an open end of the tube, the restraining lines arc the flexible ribs. In some instance, a canopy may be placed over the ribs to collect the article (e.g., precipitation) and configured to allow for storage of the article in a reservoir.

BACKGROUND OF THE INVENTION

By “umbrella”, we mean not only a portable or fixed device having acanopy protecting a person or object from rain or sun, but also a devicethat impedes the flow of some object from the area on the outside of thecanopy to the area below the canopy.

Since the appearance of the first descriptions of umbrellas—often toprotect kings and warriors from the sun—the basic principles of how theumbrella operates have remain largely unchanged: rigid members support acanopy to divert water away off the canopy and away from the operator.Early descriptions also show mechanisms relying on a user's (or othermechanical) power to extend a semi-rigid or rigid frame for theumbrella. Many more recent umbrella inventions relate to thesemechanisms, and have several inherent problems.

The first weakness occurs in windy conditions in which the umbrella mayflip inside out and needs to be un-flipped by hand. One primarydisadvantage of existing technology is that, when the umbrella is fullyextended, the furthest edges of the umbrella have little force againstthe wind. Often, the umbrellas will collapse in large gusts of wind,exposing the user to the elements.

A second weakness of existing technology is that the frame isconstructed of rigid members connected at joints. Not only are themembers subject to bending and snapping, the joints are a weak point andtend to weaken over time.

Further problems of existing technology occur when an umbrella is closedafter use. Because rain will shed down the closed canopy, the user maybe soaked by water from the top of the umbrella.

Yet another problem exists with opening of the umbrella. It is difficultto hold the umbrella high enough to avoid disturbing people near-by.Because of how a normal umbrella functions, one would need an area atleast the size of an opened umbrella around the user in order to openit. This could be an issue in a crowd.

SUMMARY OF THE INVENTION

The current invention relies on the principle that, when a longerflexible object is made to join at each end of a shorter object, thelonger object will bend and the shorter object will stretch to its tautposition. The shorter object will be referred to in the currentinvention as the “restraining member”, “restraining line”, or “line”.The longer flexible object will be referred to as a “rib”.

Using this principle, the current invention shows a number of practicalembodiments of the principle when applied to a device (e.g., umbrellasand/or umbrella-like structures) to protect an object (e.g., a person,people, a geographic area, etc.) from an article (e.g., rain, sun rays,other weather conditions, flying debris, etc.) received from above thedevice. In some embodiments, the device may be a personal devicedesigned to protect a smaller object or group of objects such one or twopeople. However, in other embodiments, the device may be design toprotect a larger object or group of objects such as, for example, agroup of people, a sidewalk, a deck or yard of a house.

In one embodiment, the device utilizes a set of shorter objects orrestraining lines and a set of flexible, sturdy longer objects or ribsstored within a tube or other container. In some embodiments, the ribsmay be affixed only to an interior sliding base within the tube, whereinterior sliding base may be attached to an exterior sliding ring on anexternal portion of the tube. Each restraining line of the set may beaffixed near each end of a rib. For instance, at a first end of the ribextending outward from the tube and at a second end of the rib withinthe tube affixed to the interior sliding base. In some embodiments, whena user pushes on the exterior sliding ring, the ribs travel toward theoutside of the tube. When the ribs have been fully extended, the lengthof each restraining line is shorter than the length of each rib whenmeasured from the tube exit to the point where each restraining lineattaches to the first end of each rib. Each rib may thereby be forced tobend due to the tension created by the length of the restraining lines.The form of each rib of the device may further be guided by a canopy(e.g., fabric, vinyl, etc.) attached to the ribs. In some embodiments,the canopy (or any other canopy described herein) may be configured withsolar cells, photovoltaic cells, and/or solar thermal collectors inorder to allow for captured energy to be converted to electricity orheat.

Since the ribs and restraining lines in the current invention areflexible and continuous, each may behave dynamically against wind force.As a tension increases against the line, that line's full test-strengthwill work against the wind. In some embodiments, since the devicedescribed herein has no joints on the restraining line or ribs, thedevice is may not be susceptible to weakness as are devices havingjoints. By attaching each restraining line at a location not at a rib'souter edge, the rib would flex in in response to wind force at theattachment point, thereby deflecting that force.

In some embodiments, where the restraining lines are stretchable (butless stretchable than the force exerted by the bent ribs), then therestraining lines will stretch when wind pressure works against thecanopy from underneath the device. This may allow the canopy to flex inresponse to wind force, but also provide a means for the device to bereturned to its normal open state.

In another embodiment, the restraining lines may be replaced by acontinuous piece of stretchable inner fabric distinct from the outercanopy. The radius of this inner fabric provides the shorter object towork against the longer ribs, but may more quickly be dispersed when thewind blows against the inner fabric. In fact, the inner fabric can beconstructed so that the entire device will flex in response to windforce is such a way as to “spill” the wind quickly. Once the wind forceis spilled, the umbrella may be brought back to its normal open state bythe normal tension between the inner fabric and the outer canopy and theribs supporting it.

Yet another embodiment describe that the ribs of the device maytelescope as the device is opened, allowing for a more compact closedposition for the device. Similarly, a mechanism allowing ribs to open ina hinged or butterfly fashion permits a compact closed position so thatthe device is more easily transported. Each of these mechanismsincorporate the use of flexible ribs—(e.g., carbon fiber-reinforcedpolymer, graphene, etc.)—bending into shape through the use ofrestraining lines. As the user moves the flexible ribs out of the tube,by manipulating restraining lines attached to the tube, and/or bymanipulating a sliding mechanism of the tube, the device may take thedesired umbrella shape due to the bending of the flexible ribs.

Other embodiments involves partially opened devices—during precipitationevents (e.g., rain, snow, etc.)—which may collect water into a reservoirfor use (e.g., watering plant, purification, agriculture, etc.) whilethe fully opened device—during excessive sun—may protect a surface fromparching. In some embodiments, the device may include a surface forcollecting energy (e.g., light rays) from the sun absorbed by thecanopy. For instance, a flexible canopy may include or be constructedwith solar cells, photovoltaic cells, and/or solar thermal collectors inorder to allow for captured energy to be converted to electricity orheat.

The term “about” or “approximate” as used in context of describingexample devices for protecting an object from precipitation or otherarticles is to be construed to include a reasonable margin of error thatwould be acceptable and/or known in the art.

As used herein, the terms “a,” “an,” and “the” mean one or more.

As used herein, the terms “comprising,” “comprises,” and “comprise” areopen-ended transition terms used to transition from a subject recitedbefore the term to one or more elements recited after the term, wherethe element or elements listed after the transition term are notnecessarily the only elements that make up the subject.

As used herein, the terms “having,” “has,” “contain,” “including,”“includes,” “include,” and “have” have the same open-ended meaning as“comprising,” “comprises,” and “comprise” provided above.

The present description may use numerical ranges to quantify certainparameters relating to the invention. It should be understood that whennumerical ranges are provided, such ranges are to be construed asproviding literal support for claim limitations that only recite thelower value of the range as well as claim limitations that only recitethe upper value of the range. For example, a disclosed numerical rangeof 24 to 36 provides literal support for a claim reciting “greater than24” (with no upper bounds) and a claim reciting “less than 36” (with nolower bounds) and provides literal support for and includes the endpoints of 24 and 36.

DETAILED DESCRIPTION OF THE INVENTION

In some embodiment, the disclosed device uses several flexible ribswhich are forced to bend by shorter restraining members in order tosupport the canopy. Each rib may be constrained by a filament line, aninner fabric, or any other object able to restrain the rib. Because thelength of the restraining member (or radius of the inner fabric) is lessthan the length of the flexible rib, the rib is forced to arch. The sizeof the arch is controlled by the difference between the length of therestraining member (or radius of the fabric) and the length of the riband their points of attachment or meeting. FIGS. 1 a-3 c show theprogression from closed to open states of this personal umbrella deviceembodiment using lines, whereas FIG. 12 shows the lines replaced by aninner fabric.

It is envisioned that several methods could be utilized to operate theflexible ribs in the device. For example, the mechanism would consist ofa filament, rope, string or wire connected to the end of a normallystraight flexible member. By pulling on the string that is threadedthrough loops secured at one or more location on the flexible member itwould cause the flexible member to bend (FIG. 6). By adjusting thestiffness of the flexible members, the location and number of loops, andhow far the strings are pulled, a multitude of device shapes arepossible. There is also potential for different groups of ribs in thedevice to be controlled independently, thereby becoming infinitelyconfigurable by the user. If sensors and motors are added to the device,it could allow the device to adjust to the wind as well as beingflip-proof.

As is evident, there are a number of variations to this line andflexible rib method. Yet another variation is, rather than using loops,a shaped fabric sleeve can be used. The flexible rib would be fixedinside a shaped sleeve, and as the string is pulled the flexible ribwould bend to follow the shape of the sleeve.

Another variation could have the string threaded through a number ofrigid hinged containers which would pivot at the hinges when tension isapplied to the string.

Yet another variation is using an inner stretchable fabric of a radiussimilar to that of the lines, and thereby replacing the lines as themechanism to exert force on the ribs as they are pushed to an openposition. This inner fabric can then act as a means to spill air thatcan be caught under the device. Not only is the angle of the innerfabric with respect to the wind less than that of the canopy, thecombination of canopy and inner stretchable fabric can flex in itsentirety with respect to the wind force.

A further possible application of the invention is to provide aneasy-to-use shade for a back-packer, as shown in FIG. 13.

Another embodiment of the invention, as shown in FIG. 14, hasagricultural uses. In its partially opened state, the device couldcollect rain water during rains and store this in a vessel for lateruse. At other times, the device in its fully opened state could protectcrops and gardens from harsh sunlight while water from the vessel isused to irrigate these plants.

In another embodiment—allowing for a more compact closed state for thedevice—instead of rigid members pushing against each other to supportthe canopy, the invention uses several flexible rib pairs which bend tosupport the canopy.

In a closed position utilizing telescoping ribs, the present inventionshows a plurality of rib pairs consisting of an upper rib containedwithin a hollow lower rib. As the device is opened, the upper rib isextracted from the lower rib. A coupling sleeve slides over the junctureof the upper and lower ribs to create a rigid unit. The drawings show anembodiment of this mechanism, with lines positioned such that theopening motion extracts the upper ribs from the lower ribs. The bases ofthe lower ribs are attached to a sliding base.

Utilizing a butterfly mechanism, the present invention also shows aplurality of rib pairs consisting of an upper rib and lower rib whichare coupled by a tension-spring butterfly-type component during theaction of opening the device. This component can be as simple as atension spring, or may be any of several other devices, 2 of which areshown in the drawings.

The coupling of the upper and lower ribs of each rib pair may beaccomplished in any of several ways. Two possible methods of many areshown in the drawings. In one, a coupling sleeve slides over thejuncture of the upper and lower ribs. In another, such as shown in FIG.16, the lower rib has a pointed end that inserts into a receptacle endof the upper rib.

Each upper and lower rib pair is constrained by a line or an innerfabric. Because the length of the line (or radius of the inner fabric)is less than the length of the flexible rib pair, the rib pair is forcedto arch. The size of the arch is controlled by the difference betweenthe length of the line (or radius of the fabric) and the length of theextended rib pair and their points of attachment or meeting.

Yet another embodiment of the invention incorporates hinged between thepaired members such that, as the ribs are ejected from the container,the lines pivot the outer ribs into an extended position, as shown inFIGS. 21 a-21 c.

As is evident, there are a number of variations to these line andflexible rib-pair methods. Yet another variation is to run the linethrough two hollow ribs comprising a telescoping rib pair. This linewould act to extend the upper rib as well as to move the coupling sleeveinto place.
